Product Overview

MB408 is an EVA-based UV-resistant functional masterbatch developed to improve ultraviolet resistance in compatible cable compounds and polymer formulations. At a typical addition level of 4%, MB408 provides a significant UV-resistance effect, supporting material systems exposed to sunlight or ultraviolet radiation.

As an EVA carrier UV protection masterbatch, MB408 offers a convenient way to introduce anti-UV functionality into cable materials and related polymer products. It is suitable for formulations where weathering resistance and protection against UV-induced degradation are required. The final addition level and UV-resistance performance should be validated according to the customer's base material, formulation and end-use conditions.

Processing & Handling Guidance

Use appropriate protective gloves and eye protection during handling. Keep the extrusion temperature at or below 230°C. Provide local exhaust ventilation or adequate ventilation during processing.

Because UV-protection performance can vary with the base material, formulation and exposure conditions, confirm compatibility, addition level and final UV-resistance performance through finished-product testing.

Drying & Storage

Under normal packaging conditions, no special drying treatment is required. If stored for an extended period in a humid environment, dry at 70°C for 4 hours in a dehumidifying dryer before use.
